What TRUE certification actually measures
TRUE applies to a physical facility and its operations. It can cover one site, multiple buildings, or multiple projects. The program can serve facilities in different markets, although some references and standards are specific to the United States. Each project must define its boundary and include all solid, nonhazardous waste generated within that boundary. Hazardous materials follow the definition used by the applicable local jurisdiction. Read the official TRUE eligibility guidance as you set the scope.
The central threshold is an average diversion rate of 90 percent or more for the most recent 12 months. TRUE counts diversion from landfill, incineration including waste-to-energy, and the environment. Acceptable pathways can include reduction, reuse, recycling, composting, anaerobic digestion, and other processing where the end product is recovered for productive use in nature or the economy. Incineration and waste-to-energy do not count as diversion for this threshold. The full published requirements also apply to each project.
A project must also meet seven minimum program requirements. It needs a zero waste policy, compliance with solid waste and recycling laws, required air, water, and land discharge permits, a base year with measurements that account for changes in the business, annual submission of 12 months of diversion data to GBCI, no more than 10 percent contamination for any material leaving the site, and a case study for publication.
Build a defensible multi-site record
Start with a site register. Record each facility address, operating period, waste boundary, material streams, service providers, permits, and local rules. Decide whether the project is one portfolio or several certifications before you combine data. A shared method helps, but it should not hide a site with a different process or a weak record. Keep collection and processing evidence tied to the site and period that produced it. A clear chain of custody links the record to its destination.
Your record should connect each material to a measured amount, a management pathway, and a destination. Keep scale tickets, weight records, invoices, transfer documents, processor confirmations, contamination findings, and explanations for estimates. Use pounds throughout your internal reporting so site teams can compare like with like. If a provider reports volume, document the conversion method and its basis instead of presenting an unsupported number.
Measure contamination at the point where materials leave the site. A clean sign system, source separation, training, inspections, and feedback can improve data as well as performance. If a material is rejected, downgraded, sent to disposal, or managed under a different rule, preserve that event. A transparent record is stronger than a clean-looking percentage that cannot be explained.
Prepare the operating system before submission
A policy should name the accountable owner, define the project boundary, set the measurement period, and describe how purchasing, reuse, prevention, sorting, and vendor review support the goal. For a distributed business, give every location the same core instructions, then add local guidance for accepted materials, language, safety, and legal requirements. Training should reach the people who buy materials, run facilities, clean spaces, load containers, and review invoices.
Anchor is a program manager, not a truck owner or yard operator. Independent permitted operators perform collection, transport, processing, and final management. Ask for the records your project needs, verify permits and destinations, and retain the underlying documents. Do not describe a downstream outcome as certain when the available evidence supports only a planned or reported pathway.
A simple internal readiness review can test the policy, boundary, 12-month data, baseline, contamination, legal compliance, permits, case study, and rating-system credits. Keep the review separate from the certification decision. Anchor can help coordinate the evidence and identify gaps, but GBCI and its assessor control the certification outcome.
Keep TRUE, Scope 3, and regulation in the right lanes
TRUE diversion records and greenhouse gas accounting answer different questions. A mass record tells you how much material was managed and where it went. It is not an emissions result. Under the GHG Protocol Scope 3 guidance, Category 5 covers waste generated in operations and requires a chosen method, emission factors, activity data, and a stated system boundary. The factor may depend on the material, treatment route, geography, and other method choices. Document those choices instead of converting a diversion percentage directly into emissions avoided.
Category 5 is about waste generated by your operations and treatment or disposal by third parties. It is distinct from Category 12, end-of-life treatment of products sold. The same material record may support both operational planning and an inventory, but it should not be placed in a category without checking what generated the waste and which boundary your inventory uses. Ask your climate reporting team to approve the method before publishing a Scope 3 number.
California requirements can also sit beside, not inside, TRUE. For covered textile producers, CalRecycle’s official timeline states that producers must join the approved PRO by July 1, 2026. It says regulations will take effect no earlier than July 1, 2028, with an approved plan due in 2030 and full PRO plan implementation in 2031. That textile stewardship timeline is not a universal rule for every waste stream or every business. Check whether your products and role are covered, then confirm current obligations with CalRecycle and qualified advisors. More broadly, use the EPA waste hierarchy to prioritize source reduction and reuse before recycling and composting, while recognizing that local conditions determine the appropriate path.
A practical certificate file for your team
Use a plain, reviewable file rather than a decorative claim. A sample certificate layout can show the project name, site or portfolio boundary, facility locations, certification program, certification level, reporting period, issue date, assessor or certification body, scope note, and a document-control field. Keep a separate evidence index that points to the policy, baseline, monthly records, contamination checks, permits, destination records, and case study. You can use this sample certificate of destruction as a reference for the value of clear fields and traceable documentation, but it is not a TRUE certificate and should not be presented as one.
Before you publish a claim, state exactly what was certified, by whom, for which period, and under which program. Do not describe a target as a certification. Do not present a waste-to-energy route as TRUE diversion. Keep renewal and annual data work on the calendar because certification depends on continuing performance.
